What if you didn't get Airdrop and Airplay with IOS 7?

I have an iPhone (obviously), and I downloaded IOS 7. I have a iPhone 4s and in the control center there's no Airdrop and Airplay. Did something go wrong in the download?

Airdrop isn't available on iPhone 4S. Apple often limit no of features on older devices to encourage sales of new devices >

IPhone 4 and 4s did not get airdrop. It is a way to urge buyers to upgrade to better phones.

Apple says it is available on an iPhone 4S or later, but I don't see it either.

According to Apple Support
You must have… "iPhone 4s (or later), iPad 2 (or later), iPad mini, or iPod touch (5th generation)
Apple TV (2nd or 3rd generation)
AirPort Express
Wi-Fi (802.11a/g/n) network"
